Perhaps you were looking at numbers from the coupe. On the sedan I have been doing things slowly step by step and then retesting to see any improvement. I have already pulled a 10.0 in the sedan...so high 9's is already a given with better than 91 octane. I will post the results when I can get closer to mid 9's in this car

Also, here is my log from my 119mph run at the track. As you can see, no huge 18+ PSI boost runs here,. Again, fully stock down pipes/intercooler/exhaust
